Abstract: A writing implement having a built-in illumination system and a light reflecting chamber includes a transparent cone of front pen tube accommodating an ink cartridge, a hollow cylindrical barrel surrounded by a light reflecting tube, a middle ring housing the light-emitting body and an annular light reflecting plate, a power chamber housed in the rear pen tube and consisting of a LED conducting wire channel and a battery room, a conducting spring, a push tube, a switching cap, and a pen cap with clip protecting the ink cartridge tip. When light switches on, a part of the emitted light passes straightly and directly toward the cone of front pen tube through the hollow of the front pen tube to light up the surface to be written on, simultaneously, another part of the light is reflected at the surface of the annular light reflecting plate and the polished mirror-like inner wall surface of the light reflecting tube and is propagated toward the cone of front pen tube.
